- Jun 15, 2026The Samuel Lawrence FoundationOpposeAdvocacy📎 Attachment
The Samuel Lawrence Foundation opposes the proposed rule, arguing that it moves too quickly and lacks sufficient oversight for microreactors. They specifically criticize the reduction of quality assurance standards from Appendix B to ANSI/ANS-15.8, the lack of clear definitions for safety terms, and the arbitrary nature of the eligibility criteria.
Read comment → - Jun 15, 2026Nuclear Energy Information Service (NEIS)OpposeAdvocacy📎 Attachment
The Nuclear Energy Information Service (NEIS), a nuclear power watchdog and environmental organization, opposes the proposed rule and urges the NRC to terminate the rulemaking process. They argue that the proposal allows for dangerous "self-regulation," fails to address systemic safety concerns regarding mobile and autonomous reactors, and ignores the complications of radioactive waste.

The Nuclear Information and Resource Service is submitting a comment on behalf of the Connecticut Department of Energy and Environmental Protection. They are requesting a 45-day extension of the public comment period due to the complexity of the proposed rule and the volume of regulatory changes being rolled out by the NRC.
Read comment → - May 1, 2026Nuclear Innovation AllianceOtherAdvocacy📎 Attachment
The Nuclear Innovation Alliance is requesting a 45-day extension of the public comment period for the proposed Part 57 rulemaking. They argue that the extension is necessary due to the complexity and length of the rule, which requires more time for stakeholders to provide detailed feedback and for the NRC to facilitate broader public engagement.
Read comment → - May 11, 2026Comment on FR Doc # 2026-08550, NRC-2025-0379-0011, from Connecticut Department of Energy and Environmental ProtectionSupportGovernment📎 Attachment
The Connecticut Department of Energy and Environmental Protection (DEEP) requests that the NRC extend the public comment period for the proposed rule on microreactor licensing from 45 to 90 days. They argue that the complexity of the proposed framework requires more time for states, technical experts, and local governments to conduct a thorough and transparent review.
